Which are the germiest spots in your house?

NSF International visited 22 Michigan homes a few years ago and took swabs of the 26 locations thought to be the most touched by people living there. These are the places where we pick up germs or leave germs behind for other family or friends to contact.

The researchers then measured the concentration of bacteria they collected from each spot.
